Review: Saved our holiday! - Daughter broke her arm just before our holiday so was advised to purchase one off these and honestly best thing we did, it worked perfectly she spend hours in and out the pool jumping in, water slides and her cast never got wet once! It was easy to take on and off and very well made. You wont regret buying it that for sure.
Review: Brilliant! - My 6 year old broke his arm just before holiday. This was a lifesaver! He used it while in the pool and on the beach with absolutely no problems. No leaks and the cast stayed completely dry. I ordered a medium for him which was perfect. It was easy to get on and off. Without this my son wouldn’t have been able to enjoy his holiday like he did. Definitely recommend 👍

## Questions & Answers

**Q: How easy is it to put on?**
A: My daughter had a cast from wrist to arm pit so was a little tricky to get round her elbow the first time. But after that it was fairly easy and worked a treat.also leant it to a friend who found it a god send x  my daughter is 9 but fairly small for her age but this size fit perfect. Hope this helps

**Q: My daugher has had a op to put her nail back on a finger and stitches. Been told not to get wet at all, going on holiday Wednesday ! How good are they**
A: They are extremely good and she will be able to fully enjoy the water. The important thing is to put them on correctly, getting all the air out by gently lowering the arm into the water and allowing the air to escape and then sealing it firmly to her arm without creases. At this point it’s completely water tight.

**Q: i have had surgery on my hand and elbow and told no water whilst in shower, as a lady with larger bones should I buy M or L**
A: We would always recommend measuring you can do so by measuring the length from the finger tips to above the affected area and the circumference is around the skin at the top of the area that needs to be covered. We would also suggest our Adult Full Arm cover but do understand if your measurements do not fit with this.

**Q: How do you get it flat against the skin by the armpit as my son is in tears with it being so tight?**
A: Sorry but we didn't have any problems.  It was tight but not so tight that it hurt so maybe your son may need the next size up.  Don't know if this is a good suggestion or not but maybe try a bit of talcum powder under the band although I am not sure if this may compromise the seal but it might be the stickiness of the rubber which is causing the issue.  Hope you manage to get it more comfortable.

### ⭐⭐⭐⭐⭐ Amazing product!
*by C***J on 30 August 2025*

This product is amazing. My son broke his arm and this allowed him to still go in a hot tub when we were away and shower with ease. It’s a little tricky to get on at first as it’s super tight but once it’s on it kept his cast completely dry. I would advise measuring the size of the cast you want to cover to ensure you get the correct size.
